SPECIFICATION forming part of Letters Patent N o. 738,855, dated September 15, 1903. Appiimion inea May 6, 1901. serai No. 58,904. (N model.)

To @ZZ whom, it may concern,.-

Be itknown that l, LAMBERT SNYDER, residing atRochelle Park, State of New Jersey,have invented certain new and useful Improvements in Mechanisms for Feeding Carbid or Like Substances in Gas-Generators, of which the following is a specification, illustrated by the accompanying drawings.

The improvement is particularly related to gasgenerators wherein powdered or lump carbid is carried in a receptacle which has a discharge-opening, through which the carbid is discharged little by little, as required, by tipping or inverting the receptacle.

The nature of the improvements will be clearly understood from the preferred form of the invention shown in the accompanying drawings, wherein- Figure 1 is a plan view of one embodiment of the invention; Fig. 2, apartial side elevation of the same; Fig. 3, a central vertical sectionthrough the carbid-receptacle; Fig. 4, a horizontal section centrally through the receptacle, and Figs. and 6 a faceview and a section of the feeding-opening of the receptacle. l

As the improvement relates particularly to carbid-feeding mechanisms and does not esspecially concern the other well-known attachments for acetylene-generators and the like, the description will be limited to the novel features.

The generator-casing 1 may be of any desired type, preferably surmounted with a shell or chamber 4, which hasra'carbidaeceptacle 5 mounted within it. The carbid-re ceptacle is mounted to turn upon an axis, as shown, one end being preferably provided with atrunnion 6 and the other with a shaft 7, which extends through a suitably-tight joint in the casing` 4 and carries a ratchet-wheel 8 outside of the casing. The ratchet-wheelS is turned by means of an operating-lever 9 and pawl 10. The operating-lever 9 may be controlled by the gasometer 3, as shown, if a satisfactory gasometer be used; but of course the invention is not limitedto a separate gasometer, it being only necessary to cause the gas generated to actuate the feed mechanism by a suitable connection, as is common in acetylene-generators. The carbid-receptacle 5 has a dischargeopening 12 and a pointed feed-lip 13. This feed-lip 13 serves to pre-v vent a sudden discharge of a large quantity of the carbid, because as the receptacle is inverted to feed, as shown in Fig. 3, the carbid will gradually begin to pour at each side of the point of the lip 13 instead of pouring freely out of the entire width of the opening 12. As will be seen from Fig. 3, the weight of the carbid tends to rotate the receptacle in a direction to raise the feed-opening 12 and stop the feeding. In order to prevent too wide a range of movement of the lever 9 in feeding the carbid from the receptacle, a second pawl 15, pivotally secured to the casing 4 by a pin-andslot connection, as shown, is employed. The slot is not absolutely necessary, but it permits the turning backward of the ratchet 8 for a greater distance than would be possible if the slot were not present. The pawl'l, limiting as it does the backward turning of the carbid-receptacle, enables the pawl 10 to pass successive teeth of the ratchet S from time to time as the receptacle is gradually emptied. The lever i) is weighted at its left-hand end, so as to cause it to follow within limits the motions of the gasometerbell An arrow-head or other marker on the ratchet S, correspondingin angular position to the opening 12, enables the operator to tell how far the carbid-receptacle has been emptied, because it indicates the position of the discharge-opening 12. For reiilli'ng, a charging cover 16 is provided in the top of the casn ing 4. Vhen the receptacle is empty, it may be turned until the arrow points toward the charging-cover 16, and then the cover may be removed and the charge inserted through into the receptacle 5 through its opening 12.

From the foregoing it will be seen that my invention comprises mechanical means for turning the holder in one direction to cause feeding as it is required from time to time 1,

and means for limiting` the backward movement of the holder in the reverse direction.

l do not mean to restrict myself to the precise form of mechanical elements employed for accomplishing either of these functions.

I do not herein claim, broadly, the pivotallymounted carbid-holder shown and described and claimed in the copending application of Charles Goodyear, Serial No, 58,S81 filed May ICO discharge opening, an operating -lever con- York, N. Y.

nected to rotate the holderin a direction to feed the carbid through the discharge-opening, the Weight of the carbid tending to rotate the holder in a direction to raise the discharge-opening and stop the feed, and means for permitting a limited rotation of the holder under the Weight of the carbid in a direction to raise the discharge-opening, for substantially the purposes set forth.
